<p>A method for coded multiplexing is disclosed in the present invention. The method performs coded multiplexing transmission by using parallel linear or nonlinear code which code rate is higher than 1. When code rate is higher than 1, there is one-to-one corresponding relation between the parallel code input sequence and the parallel code output sequence. The parallel code deviates limit area, and all parallel code multinomial sets are coprime with respect to each other. The method includes the following steps: constructing code matrix B, the matrix B includes K code vectors; forming parallel transmitted K sets data, the K sets data corresponding to the K code vectors; performing convolution code for each set data and the corresponding code vector of the set data, code constraint length is L; adding the convolution code results of the K sets data so that obtains N dimension code output vector; receiving the N dimension code output vector and performing sequence checking to them; the K, N, L are parallel code basic parameters. The present invention can improve the system capability and frequency efficiency by employing the linear or nonlinear code transmission which code rate is higher than 1.</p> |
